There are challenges associated with using Silicon Anode Battery as an anode material. One major issue is the significant volume expansion and contraction of silicon during the charge and discharge cycles. When lithium ions are inserted into the silicon anode during charging, the silicon expands, and during discharge, it contracts. This repeated expansion and contraction cause the silicon to crack and ultimately degrade the performance and cycle life of the battery.
To overcome this challenge, researchers and engineers have been exploring various strategies. One approach is to use nanostructured silicon materials, such as silicon nanowires or silicon nanoparticles. These nanostructured materials can accommodate the volume changes more effectively, reducing the risk of cracking. Additionally, coating the silicon particles with a protective layer or using binders and conductive additives can help mitigate the mechanical stress on the silicon anode.
